Use when defending the research design of an American Political Science Review (APSR) manuscript — causal identification for quantitative work, case selection and process tracing for qualitative work, experimental and survey-experimental design, or formal-empirical linkage. APSR judges each tradition on its own terms. Strengthens the design; it does not write code.

First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/apsr-research-design/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

Research Design (apsr-research-design)

APSR accepts many methodologies but is demanding about each. The design must credibly connect the argument (apsr-theory-building) to evidence. This skill is mode-aware: pick the section that matches your work and defend it against the strongest alternative explanation.

When to trigger

  • Specifying identification, case selection, or experimental design
  • A reviewer questioned causal claims, case choice, external validity, or a confound
  • Preparing a pre-analysis plan or a Registered Report Stage 1 design
  • Justifying why your design adjudicates the rival account from apsr-literature-positioning

Quantitative / causal inference

  • Identification first. State the estimand and the assumptions that license a causal reading (ignorability, parallel trends, exclusion, continuity). Defend them, don't assert them.
  • Designs: experiments (incl. survey/conjoint), DID/event study (use modern staggered-adoption estimators, not naive TWFE), IV (first-stage strength, exclusion, weak-IV-robust inference), RDD (density/manipulation tests, bandwidth robustness), matching/weighting with balance + sensitivity.
  • Inference: cluster at the level of treatment assignment; randomization inference for experiments; multiple-comparison adjustment when testing many implications.
  • Sensitivity: how strong must an unobserved confounder be to overturn the result?

Qualitative / case-based

  • Case selection justified by design logic (typical, deviant, most/least-likely, paired comparison) — not convenience. Say what the case is a case of.
  • Process tracing with explicit tests (hoop, smoking-gun, straw-in-the-wind); state what evidence would have disconfirmed the argument.
  • Source transparency: archives, interviews, fieldnotes — plan how they will be documented and cited (see apsr-transparency-and-data-policy).

Experiments (lab / survey / field)

  • Preregister the design and primary analyses; report power/MDE; pre-specify subgroups.
  • Address attention/manipulation checks, attrition, and ethics/IRB and consent.
  • For survey experiments: sampling frame, treatment realism, and generalization claims.

Formal-empirical linkage

  • Make the empirical test follow from the model's comparative statics, not a loose analogy.
  • Distinguish predictions that are unique to your model from those shared with rivals.

The adjudication test (APSR-specific)

For the single strongest rival explanation, write one sentence: "If the rival were true rather than my argument, the data would look like ___; instead they look like ___." If you cannot, the design does not yet identify the contribution.

Execution bridge (StatsPAI / Stata MCP)

Estimate and audit the design, don't only describe it. Full map: execution-with-mcp. APSR is general-interest political science — observational causal designs (DiD/IV/RDD) and survey/field experiments alike; cluster by the right unit and foreground identification.

  • detect_design → recommend → fit with as_handle=true → audit_result.
  • Observational causal claims: staggered DiD (callaway_santanna / sun_abraham + bacon_decomposition + honest_did_from_result); IV (effective_f_test + anderson_rubin_ci); RDD (rdrobust + mccrary_test).
  • Experiments: randomization-based inference, romano_wolf for many-outcome family-wise control, and mediate for mediation (not naive controlling-away).
  • Sensitivity: oster_delta / sensemakr for observational claims.

Report the effect size in interpretable units; route the full battery to the appendix/supplement. A run end-to-end (synthetic data, real returns) is in the JF execution walkthrough.

Anti-patterns

  • Naive TWFE on staggered treatment; clustering at the wrong level
  • "Causal" language on a design that only supports association
  • Convenience case selection dressed up as theory-driven
  • Conjoint/survey experiments over-generalized to real-world behavior with no caveat
  • A design that cannot distinguish your argument from the leading alternative

Output format

【Mode】quant-causal / qualitative / experiment / formal-empirical
【Estimand or claim】what is being identified/shown
【Key assumption(s)】and how each is defended
【Rival ruled out】the adjudication sentence
【Robustness/sensitivity】planned checks
【Next】apsr-data-analysis
